Science of Ben Stein's Nazis

Ben Stein points out correctly that the Nazis used evolutionary theory in part of their justification for their final solution. Stein infers that such a connection is further evidence that evolution is false and dangerous.

But the Nazis only used evolutionary theory in rhetoric. They didn't build a better bomb using evolutionary theory.

By contrast, they did build better weaponry using Newtonian mechanics. If we are to follow Stein's inference, then Newtonian mechanics should be considered false and dangerous due to this Nazi connection. Reductio ad absurdum.
